dhiraj replied to Nicholas Witham's discussion Why are we starting to use companion computers? in Companion Computer Working Group
"IMHO there's two layers where you can tinker with drones, one is the core flight (autopilot layer) and the other one is applications which use drones for some task. Once your drone is ready to listen to your commands, what would you like it to do…"

dhiraj replied to Nicholas Witham's discussion How do I decide what platform to use? in Companion Computer Working Group
"Hi Nicholas,
I'm a developer from FlytBase team.
I would suggest going for odroid, rather than Edisson, especially if you want to use computer vision onboard.
Dronekit python is a good project if you want to write python scripts to control the…"

"@Brian awesome build! Overall system looks very professional, especially the work done on spraying mechanism."

dhiraj commented on Chris Anderson's blog post NavStick FlytPod now on Indiegogo
"@ Alex Wright
Yes that is a STM32 processor, doing job of a conventional autopilot. It runs fork of Px4 flight stack. And talks with Odroid over serial connection. "

dhiraj commented on Scott Shawcroft's blog post Introducing Polystack Flight Controllers
"That looks interesting! And seems like a lot of work, from your blog.
But is it really necessary to separate out common features which you can easily get in a single packaged autopilot? Is there any special configuration required at basic autopilot…"

dhiraj commented on dhiraj's blog post Flight Computer with Built-in OpenWRT WiFi Router!
"@Serge Contal, the fan is not for Wifi router, its for single board computer / companion computer. Actually we also wanted to avoid putting it, but it seems inevitable given the Octacore processor at 2 GHz. Until now we haven't faced any performance…"

"Thanks @Jerry Giant, thats quite useful info.
The hardware is closed but the access to router is open and documented here. So practically anybody can configure wifi board with any other firmware if they want. Currently it is interfaced using…"

"@Pmarche Not yet. But I have read few other guys doing it. FlytPOD runs linux so wont be difficult to get it working."

"@Bill Bonney Yeah, I too believe that range isn't relevant. With directional high gain antennas and stuff you can increase it significantly.
Our purpose of bringing this FC is not to compete with other long range solutions.
FlytPOD is for developing…"

"@naish We haven't yet done any long range test but we have very successful results within 250 meters, LOS.
Soon planning on testing range between two drones with FlytPOD, beyond 500 meters."

"@James, Yes we intend to use wifi as only datalink, however telemetry port is available as well.
We have tested it for 250 meters with ping time of 5ms with ASUS router on ground. Baud rate wouldn't be a good major to rate it on, but we have tested…"

dhiraj commented on dhiraj's blog post Flight Computer with Built-in OpenWRT WiFi Router!
"@James, even if we go for 5.8 GHz, we still will have to use 2.4 GHz. Because 5.8 GHz works very poorly through obstructions. And there will always be some low bandwidth crucial data that you want to get on ground even if high bandwidth data link…"

"@James We are planning on using dual band for bandwidth's sake.
Even though it seems obvious, we haven't yet came across any serious interference issues since last 6 months.
Maybe more number of long range tests can tell us more about it. "

"@ Achal Thanks Achal,
For general info this wifi config widget is released as part of the latest update to flytOS.
@Bill Thanks Bill. FlytPOD Beta program is still running. You can apply to it here.
The only DIY version know is WRTnode, but I am not…"

"Know more about OpenWRT powered WiFi on FlytPOD."

dhiraj posted a blog post
Traditionally, drones have used low bandwidth radio communication to connect to ground devices. Last year, when we started building the FlytPOD Flight Computer (next generation autopilot), we wanted to equip it with a better communication system.…
